This enhancement to quagga (which is in cerowrt-sugarland) adds back
an ability we lost in converting from the original babeld.
I used it to allow ipv6 traffic to be routed over ipv4 natted links in
the bloatlab. (by blocking ipv4 distribution over the shared external
wire but allowing ipv6) No doubt there are other uses.
One of my thoughts with this technology is to be able to share your
ipv6 routes/addresses with your neighbor, be your ipv6 connection be
native or tunnelled.

Hello,
It's now possible to distribute both v4 and v6 on quagga's babeld in
quagga RE-testing-0.99, but the syntax is affected.
The definition of an access/prefix-list doesn't differ: the kind (v4
or v6) is explicit, e.g. :
access-list toto deny any
ipv6 access-list toto deny any
(note that you have in this example the same name ("toto") for two
different lists: one v4, the other v6)
You must specified v4 or v6 for the redistribution:
distribute-list toto /* will distribute the v4 "toto" list */
ipv6 distribute-list toto /* will distribute the v6 "toto" list */
For ripng, which use only v6, you can continue to use the v4 syntax :
distribute-list toto /* will distribute the v6 list */
ipv6 distribute-list toto /* same */
Here is a complete example:
password zebra
enable password zebra
router babel
network eth0
distribute-list global_ipv4 in eth0
distribute-list local_ipv4 out eth0
ipv6 distribute-list local_ipv6 out eth0
redistribute kernel
redistribute connected
redistribute static
redistribute ripng
access-list local_ipv4 permit 1.2.3.0/23
access-list local_ipv4 deny any
access-list global_ipv4 deny 1.2.0.0/16
access-list global_ipv4 permit any
ipv6 access-list local_ipv6 permit 2001:2:3:4::/64
ipv6 access-list local_ipv6 deny any
